As hard as JCM works to be proactive and make repairs to prevent failure there are certain items such as electrical components that do not show wear or potential failure. We do our best to suggest stocking spare parts and giving phone support to get your machine back up and running asap but in the event that you need a specialist on-site asap to make these repairs we are normally there within 24 hours. We understand that these machines need to be operating at their best everyday.
